MILKING APPARATUS.

Specification of Letters Patent.

Patented March 17, 1908.

kApplication filed November 30, 1907. Serial No. 404,608.

To all whom it may concern:

Beit known that I, AUGUSTUS W. HARDY, a citizen of the lUnited States,residing at May, in the county of Brown and State of Texas, haveinvented a new and useful Milking Apparatus, of which the following is aspecification.

This invention relates to devices of that class employed for milkingcows, and has for its princlpal object to provide a novel form ofmanually operable device by which pressure may be exerted on the teatsfor the purpose of forcing out 'the milk, the degree of pressure beingdirectly under the control of the operator.

A further obj ect of the invention is to provide a device of this classin which the milking may be accomplished without contact of the hands ofthe o erator with either the teats or with the mi k, thus minimizing thedanger of the introduction of disease germs or bacillus into the milk.

A still further object of the invention is to provide a manuallyoperable device of this class in which a pair of hinged or similarlyconnected members are arranged to form a milk duct, and which carry atthe top rollers for en aging the teats.

Wit these and otherobjects in view, as

will more fully hereinafter a pear, the invention consists in certainnovel features of construction and arrangement of parts, hereinafterfully describe illustrated in the aocompanying drawings, andparticularly pointed out in the appended claims, it being understoodthat various changes in the form, proportions, size and minor details ofthe. structure may be made without departing from the spirit orsacrificing'any of the ad- 40 vantafres of the invention.

In tthe accompanying drawings z-Figure l is a perspective view of amilking apparatus constructed in accordance with the invention. Fig. 2is a longitudinal sectional view ofthe same. Fig. 3 1s a sectional planview on the line 3-3 of Fig. 2. Fig. 4 is a ers ective view illustratinga slight modi cation of the invention. Fig. 5 is a longitudinalsectional view of the same. Fig. 6 is a sectional plan view on the line6'--6 of Fig. 5.

Similar numerals of reference are employed to indicate correspondingarts throughout the several figuresfof the rawings.

k n carrying out the invention, a pair of arms 10 formed of any suitablematerial'are connected at the lower end by a hinge 11 that isdisposed atone side of the arms, and the two arms are normally held separated by apair of springs 12. The top of each arm is ifurcated, forming ears forthe passage of pins 15, on which are mounted rollers 16, that are formedof hard rubber or other suitable material, these rollers being designedfor engagement with the teats of the cow. The central ortions of thearms are somewhat reduce( in cross section and are rounded so that theymay be conveniently grasped in one hand, and the operator in practlcemay wear sterilized gloves, so as to avoid direct contact of the handwith the teats or milk.

The inner walls of the arms are provided with channels 17 through whichthe milk may flow from the upper to the lower ends of the arms anddirected into a suitable pail or other receptacle. In order to preventthe lateral escape of the milk, each arm is provided' with projectingwin s 18 that overlap so as to form a practicay closed passage from topto bottom of the arms. In practice, the device is grasped in one handand the arms being opened by the springs, the rollersare placed oneither side of the teat and forced together under any suitable degree ofpressure for the purpose of expelling the milk, the device beingmanipulate in practically the same manner as practiced in hand milking.

In the construction illustrated in Figs. 4, 5 and 6, the milk device isformed wholly of sheet metal. The handle members 10 are in the form oftransversely curved sheet metal plates, the edges of which continuouslyoverlap so as to form a wholly inclosed channel from top to bottom. Theupper ends of these plates are provided with integral ears which areperforated for the reception of the spindles 15 of the teat engagingrollers 16. At the lower ends of the plates, rivets 11 are employed,these rivets forming hinge points in order to permit free movement ofthe members toward and lfrom each other. Near theV upper end of each ofthe members 10 is a pair of projecting lugs 20 and extending betweenthese lugs are compression springs 21 that serve to spread the membersin order that the rollers may enga e the teat.

I c aim 1. A milking device comprising a pair of arms, the inner wallsof which are channeled to form a milk passage, and rollers arranged atthe upper ends of said arms for engagement With the teat.

2. A milking device comprising a pair of arms, the inner Walls of whichare channeled to form a milk passage, overlapping Wings at the outeredges of the arms, and rollers journaled at the upper ends of said armsfor engagement with the teat.

3. A milking device comprising a pair of arms hinged at their lowerends, and the inner Wal s of which are channeled to form a milk passage,Wings arran ed at the outer edges of said arms and over apping to closei the passage7 springs tending to maintain the arms in open position,and a pair of rollers journaled at the u per ends of the arms forengagement with t e teat.

4. A milking device comprising a pair of channeled arms, pivotedtogether, and the edges of which overlap to form a continuous closedchannel from top to bottom of said arms, and teat engaging devices atthe upper ends of said arms.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.
